WRAPPING-MACHINE.

Specification of Letters Patent.

Patented Oct. 7,1913.

Application filed April 6, 1904. Serial No. 201,861.

To all whom it may concern Be it known that I, SYDNEY I. PnEsco'r'r, acitizen of the United States, residing at New York, county of New York,and State of New York, have invented certain new and useful Improvementsin \Vrapping- Machines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in wrapping machines, andhas for one of its objects to produce an improved form of wrappingmechanism which will be simple in construction and efficient in operation.

A further object of the invention is to produce an improved wrappingmachine in which the wrapper shall be delivered to the wrappingmechanism by means of a belt and on which the wrapper is held, the beltbeing rotated to deliver the wrapper and the wrapping mechanism takingthe wrapper from the belt.

A further object of the invention is to produce an improved wrappingmachine in which the wrapper is presented to the wrapping mechanism by abelt upon which the wrapper is held, either the belt or the wrappingmechanism, or both, during the wrapping operation, being given suitablemovements to properly present the wrapper to the wrapping mechanism.

Nith these and other objects in view, the invention consists in certainconstructions and in certain parts, improvements and combinations, aswill be hereinafter fully described and then specifically pointed out inthe claims her unto appended.

in the accompanying drawings Figure 1 is a plan view of so much of awrapping mechanism as is necessary to an understanding of the invention,the wrapping mechanism proper being removed. Fig. 2 is a side elevation,partly in section, of the construction shown in Fig. 1, the wrappingmecha nism being shown in its proper position in said view. Fig. 3 is anend view of the construction shown in Fig. 1. Fig. i is a detail view ofthe mechanism for transferring the wrapper to the wrapper presentingbelt. Fig. 5 is a detail sectional view illustrating more particularlythe blast mechanism for transferring the wrapper from the belt. Fig. 6is a detail view of one of the cams and its connections. Fig. 7 is adetail sectional view of the mechanism for swinging the presenting belt,and Fig. 8 is a sectional detail view illustrating a modification.

Referring to the drawings which illustrate a concrete embodiment of theinvention, 1 indicates the frame which may be of any suitableconfiguration. In the construction shown, the wrapper, which is to bepresented to the wrapping mechanism hereinafter described, is cut in themachine by a die and a cooperating member, and in the preferredconstruction, the sheet or material from which the wrapper is cut willbe retained in position with respect to the die by suction, though othersuitable retaining devices might be employed. In general, the cuttingmechanism, in the preferred form, will be substantially similar to thatillustrated in the patent to R. L. Patterson and George Arents, Jr., asthe assignees of Oluf Tyberg, No. 654,203, dated July 24, 1900.Reference is made to this patent for a detailed description of themechanism.

For the purposes of the present application it is sufficient to say thata leaf of tobacco is placed on a perforated bed 2, said bed beingprovided with a knife 3 of suitable configuration. A suitable suctionproducing mechanism, such, for instance, as described in the patentreferred to, is caused to hold the leaf on the bed, after which thewrapper is cut by a roller 4 supported on an arm 5, this arm beingmounted on a carriage 6. This carriage reciprocates in suitable ways 7on the bed, this reciprocating movement being produced by a lever 9which is connected to the carriage by a link 10. This lever is mountedon a shaft 11 suitably sup ported in the frame, said shaft having an arm12 extending therefrom. This arm is connected by a link 13 to one of thea ans 14 of a bell-crank lever lil5, said lever being pivoted to a stud16 mounted in the frame of the machine. The arm 15 of the bell cranklever is provided with the usual cam roller which engages a cam groove17 in a suitably formed cam mounted on a cam shaft 18 suitably supportedin the frame.

After the wrapper has been cut, it is, by mechanism which will behereinafter described, transferred to a wrapper presenting means. Thismeans, in the preferred construction embodies a wrapper presenting beltwhich may be mounted in various ways and operated by widely varyingconstructions, and the wrapper may be held thereon in various ways. Inthe preferred form of the construction, and as shown, however, the belt,which is marked 19, will be provided with perforations 20 so that thewrapper may be held thereon by suction. While the suction mechanism maybe, as has been suggested, of any suitable form, in the preferredconstruction and as shown, the belt will be mounted in a box 21 having aslotted top and bottom, the edges of the slots being shouldered, asindicated at 22, to form a guide for the belt. As illustrated, the beltis mounted on rollers 23 suitably supported in the box, and in thepreferred construction, these rollers will be provided with grooves 2%which register with the rows of perforations in the belt.

The wrapper after being cut in the manner described hereinbefore or byany other suitable mechanism must be transferred to the belt. This maybe accomplished in any suitable way and will preferably be accomplishedby moving the bed on which the wrapper is cut. The mechanism by whichthe bed is moved to bring it into position to transfer the wrapper maybe of any suitable description As shown, the bed. 2 and knife 3 aremounted on a plate 25 said plate being provided with a dove-tailedprojection 25 which moves in a suitable groove 26 in a bed 26 mounted onthe frame of the machine. The plate 25 has mounted on it a stud 27, saidstud being engaged by a forked lever 27 on a vertical shaft 28 suitablymounted in the frame of the machine. This vertical shaft has extendingtherefrom an arm 29 which is provided with a bowl 30 which engages witha suitable cam groove 31 in a cam mounted on the shaft 18 beforereferred to. d

The suction is produced in the bed by means of a suitable suctionmechanism, such, for instance, as a fan, not shown, the connections fromthe fan to the cutting bed including suitable pipes, such, for instance,as pipes 32. In order that the suction may not be cut off during themovement which the bed is given to bring the wrapper into suitableposition to be transferred to the belt, suitable telescopic connectionsare provided, these connections including short tubes 33 (see Fig. 4)which are connected to the bed, said tubes telescoping into the pipes 32when the bed is given its movement.

The movement of the cutting bed hereinbefor'e referred to positions thewrapper in the particular construction shown, beneath the under run ofthe belt, so that it may be readily transferred to the belt. Theconstruction by which the transfer of the wrapper from the cutting bedto the belt is effected may be of any desired character, but it willpreferably be effected by moving the 1 bed. In the construction shown,the bed is provided with a depending lug Bet (see Fig. e and dottedlines in Fig. 1) which moves in suitable guides 35 secured to the plate25. hen the cutting bed has been shifted in the manner hereinbeforedescribed so as to bring the cut wrapper into position beneath the underrun of the belt, this depending lug 8 1 comes over and registers with aplunger 36 mounted on the bed 28 which bed is suitably secured to themain frame. This plunger 36 has on its lower end a collar 37 which isengaged by a forked lever arm 39 extending from a hub a0, said hub beingsupported on a stud 41 carried on a bracket attached to the main frameof the machine. This hub 10 has extending from it a second arm 12 whichis provided with a suitable bowl engaging with a cam groove in a cam 43mounted on the shaft 18 before referred to. The cam is so shaped thatwhen the cutting bed carrying the cut wrapper comes into positionbeneath the under run of the belt, it will, through the mechanismdescribed, raise the bed, thus throwing the wrapper up against thesuction belt which at this time will be stationary. While the suctionmight be out ofi to permit the transfer of the wrapper, in the preferredform of the construction. the suction operating through the perforations20 in the belt will. be strong enough to take the wrapper from thesuction bed.

After the wrapper has been transferred by the mechanism described, or byany other suitable mechanism, to the belt, the belt will be caused totravel in order to bring the wrapper into proper position sothat it maybe presented to the wrapping mechanism.

he movement of the belt may be effected by agencies which difier widelyin construction. In the construction shown, one of the rollers 23 hasits shaft 44- extended outward from the box and to this shaft isconnected a flexible shaft 45, the connection being effected by means ofa collar 40 or in any other desired manner. This flexible shaft e5 hasits other end supported in a bearing 47 which is supported in a bracket18 0X- tending outwardly from the machine frame. The end of the shaft 45is provided with a spiral gear 19 which meshes with another spiral gear50, this spiral gear being supported on a stud 51 mounted in the mainframe of the machine. Mounted on this stud 51 is a gear 52, the saidgear being fast to the spiral gear 50. This small gear 52 is at propertimes actuated by a segment rack 53 secured to a disk 54 mounted on theshaft 18 before referred to. It will beseen that through theconstruction which has just been described, the belt will be given anintermittent traveling or rotating movement, the segment rack 53 beinglong enough to produce a sufficient movement of the belt to cause thewrapper to be delivered to the wrapping mechanism.

The wrapping mechanism may be of any desired construction, and may belocated in any desired position with respect to the belt. In thepreferred construction, however, and as shown in Figs. 2 and 3, thewrapping mechanism will be located over the belt. The construction ofwrapping mechanism illustrated in Figs. 2 and 3 is in its generalfeatures of the type disclosed in the patent to Reuse No. 552,447,granted December 81, 1895. The wrapping will be efiected by means ofpairs of intermeshing aws 55 operating through suitable gearing in themanner generally indicated in the said Reuse patent.

In the construction shown in Fig. 8, the wrapping mechanism indicated isof the ordinary roller form, the rolls being marked 56, and these rollsare located at one end of the belt instead of over it, as is the case inthe other figures. It is obvious that the wrapping mechanism might beplaced under the belt if desired, but this modification being obvious noillustration is deemed neccssary.

The wrapping mechanism may take the wrapper from the presenting belt invarious ways, but there will preferably be emloyed positive agencies fortransferring one end of the wrapper to the bunch or other object in thewrapping mechanism. In the construction shown, this transferringmechanism consists of a blast mechanism. In the construction shown inFigs. 1, 2, 3 and 5, there is provided a blast pipe 57, said pipecommunicating with a suitable blast mechanism, not shown, and this pipecommunicates with a guide 58 which is formed in one of the walls of thebox 21. Connecting with this guide is a short bent pipe 59, the openingin which registers with a line of the perforations 20 in the belt. Thisblast may act either constantly or intermittently, as desired. In theconstruction referred to, when the point of the wrapper reaches theproper position beneath the jaws it also overlies the opening in theblast pipe and is blown upward by the blast into the grasp of the jaws.

The construction shown is intended for wrapping tapering cigars. Inorder that the wrapper may be properly presented to the cigar, means areprovided for effecting a relative angular movement between thepresenting belt and the wrapping mechanism during the wrappingoperation. While this might be accomplished in various ways, in the bestconstructions, it will be effected by swinging the presenting belt. Themechanism for thus swinging the presenting belt may be varied withinwide limits. In the construction shown, see more particularly Figs. 3and 7, the frame is provided with a circular boss or collar 60 and thebox 21 is provided with a downward projecting tubular extension 62 whichprojects through the boss, the box being provided with a shoulder so asto be seated on the boss. The lower end of this tubular extension 62 isprovided with a segment gear 63 which is engaged by a segment 64 mountedon a lever 65, said lever being pivoted on a stud 66 depending from theunder side of the frame. The lever carries on its other end a bowl 67which engages with a cam groove 68 in a cam mounted on the shaft 18before referred to.

hen the machine is to spirally wind. a wrapper about an article to bewrapped, as is the case in wrapping cigars, for instance, a relativetraversing movement will be effected between the wrapper presenting beltand the wrapping mechanism. While this may be effected in various ways,in the preferred construction, it will be effected by causing thewrapping mechanism to receive a bodily traversing movement. Thetraversing movement may be eliected in any desired manner, as, forinstance, in the manner illustrated in the patent granted to Pattersonand Arents, as assignees of Oluf Tyberg, No. (354,195, dated July 24:,1900. In the construction illustrated, the wrapper carrying jaws and thegears and shaft which operate them are mounted in a frame 69 mounted ontwo rods 70 which are sup ported in arms 71 extending upward from theframe of the machine. The gears which drive the jaws receive theirmotion primarily from a long gear 7 2 mounted on a shaft 73 ournaled inthe arms 71, this shaft being driven in any suitable manner, as, forinstance, by a belt pulley 7a. One of the gears which forms a part ofthe train which drive the jaws, as, for instance, the gear marked 75, isconstantly in mesh with the long gear 7 2. The traversing movement ofthe wrapping mechanism is effected by means of a lever 76 pivoted at 77in a bracket on the side of the frame, this lever being connected to theframe 69 by means of a link 78. The other end of this lever 76 isprovided with a bowl which engages a suitable groove in the side of acam drum, this drum being the one in which the cam groove 68 beforereferred to is formed.

Changes and variations may be made in the mechanisms by which thisinvention is carried into effect. The invention is not, therefore, to belimited to the specific details of construction hereinbefore describedand illustrated in the accompanying drawings.
